Pan Arab Osteoporosis Society Guidelines for Osteoporosis Management.

Osteoporosis is the most common bone disease in humans. With its related fragility fracture, it represents a major public health problem in our region, with a significant medical and socio-economic burden. The high prevalence rate of vitamin D deficiency, the increase in life expectancy, the low socioeconomic level and the significant restriction to access to health care in some countries represent the major causes for the increasing prevalence of osteoporosis and incidence of fragility fractures in the Arabic countries.

Predictors and relationships of serum 25 hydroxyvitamin D concentration with bone turnover markers, bone mineral density, and vitamin D receptor genotype in Emirati women.

Objectives: To determine factors influencing serum 25 hydroxyvitamin D (25OHD) concentration and relationships between serum 25OHD concentration, bone turnover markers, bone mineral density (BMD), and vitamin D receptor (VDR) genotype in Emirati women.

Methods: Serum 25OHD, parathyroid hormone (PTH), osteocalcin (OC), vitamin D binding protein (VDBP), and urinary deoxypyrdinoline (UDPD) concentrations and VDR genotype were determined in Emirati women volunteers who were participating in a study aiming at establishing a reference database for BMD.

Results: Serum 25OHD concentration in the 259 women volunteers was 25.

Bone density estimates and risk factors for osteoporosis in young women.

The bone mineral density (BMD) of the calcaneus was estimated in 185 young women from the United Arab Emirates, using SAHARA ultrasound. All participants completed a questionnaire on factors potentially associated with osteoporosis. In all, 29 (15.

Correlation of quantitative ultrasound parameters of the calcaneus with bone density of the spine and hip in women with prevalent hypovitaminosis D.

Quantitative ultrasound (QUS) of the calcaneus correlates modestly with axial dual-energy X-ray absorptiometry (DXA). Because bone mineral density (BMD) might be influenced by vitamin D status, we assessed the correlation between both techniques in 56 Arabian women, a population with high prevalence of hypovitaminosis D. The speed of sound (SOS), broadband ultrasound attenuation (BUA), and estimated BMD of the right calcaneus were determined by QUS.

Cerebral blood flow in alcohol withdrawal: relation to severity of dependence and cognitive impairment.

Background: Alcohol dependence affects cerebral function in complex, still unsettled ways.

Methods: Thirty exclusively alcohol-dependent patients in various stages of withdrawal and 25 matched controls were examined for regional uptake of 99mTc-HMPAO in nine homologous regions of the cerebral cortex by single photon emission tomography (SPET). Image analysis reports regional uptake/uptake in homologous hemisphere.
